Description

Designed for optic-cut setups where factory components can lead to sluggish feeding or nozzle drag, the Pro Arms 130% Air Nozzle Return Spring ensures rapid, positive resetting of the loading nozzle inside the blowback housing. Tuned specifically for Umarex / VFC Glock MOS platforms, including G17 Gen 5 MOS, G19 Gen 5 MOS, and G45 MOS models?carrying red dots like RMR or Docter footprints- it delivers 130% enhanced tension over stock specifications to overcome tight hop-up bucking friction. Direct drop-in installation using high-tensile, heat-treated spring steel prevents nozzle sticking and eliminates mid-cycle jams during high-cadence firing under green gas and propane pressures, making this single-spring upgrade essential for crisp, flawless cycling.
